This is a rather interesting and unusual design which features irregular-shaped marble tiled on the perimeter around the tub complemented by wood for the rest of the floor. It’s a way of delineating the tub area in the case of an open space bathroom.

Even if you choose small tiles or mosaic designs for your bathroom floor, you can still use marble to create an elegant and refined look that matches other features in the room. Consider light colors if you want to make the space appear larger.

Of course, the open floor plan doesn’t get its popularity due to the number of rooms but rather the way that those spaces function within the larger whole. If you’re one to prefer privacy and, perhaps, greater organization (e.g., more built-ins and storage), having fewer rooms with which to work could put your space at a disadvantage.
